Security concerns are especially high due to the fact that the terrorist act coincided with the international Global Policy Forum, which has attracted dozens of top officials, politicians, businessmen, scholars and experts from over the world to the city of Yaroslavl, not far from Moscow.

Presidential Envoy to North Caucasus Aleksander Khloponin has announced that the investigators of the attack already have unearthed a few clues, but called on the region’s residents to be alert and attentive.

“We have several clues regarding the people who committed this crime; we are working on them,” Khloponin assured.

“We should find and punish the organizers of this evil deed. We should not stay indifferent to what’s happening around us. That is why we should be alert and actively resist those who think they can rule our destinies, who do not want our children to have a normal future,” he added.

Meanwhile, Russian Prosecutor General Yury Chaika took the investigation of the terrorist act under his personal control.
